one edge adapted -to overl-ip t-he coacting edges,'sucli plates being` numbered 15 M i? 50 with projecting arms 26; said ing their outer ends bent 'inwardly to fornil center thereof, the uppermost aiid lowerniost of said notches communicating with the ends -of the easing, while the central notch has eoniniunication with the iiieetingtedge thereof, these notched openings 'being provided on4 the edge of the easing which is disposed interiorly of the opposite edge; and secured to the inner wall of thecasing disposed adjacent to `one horizontal edge thereof are bearing brackets 17, said bearing brackets being secured a short distance froinjthe edge lof the plate and adjacentv to'thef notched openings 16; said brackets having fvertically disposedpivots 1S disposed therein. Secured adjacent the upper and lower ends of the 'casing and upon the opposite coacting edge are bearing brackets 19,-"inwhich is mounted a vertical shaft 20, -having rigidly secured thereon,` adjacent to .fthe bearing brackets 17, crank arms 2l', whiclifare disposed ,over the pins 18, so that rotation of the shaft 2O through the. niediuni of the operating handle 22,'will .rotate fthe arnis 21 and 'draw the sections of the casing together` 25 thereby-tightly clamping it ifndg'i'ts annular bell'14 disposed upon the upperface there of, butI may omit this-belliI portion and v simply rotate the shaft 20 to any desired position at' which position it is held by the the 'bearing brackets 19 from thexi'nner sides [transversely thereof and engage with Athe sha-ft 20,so as to frictionally' hold it in any desir'edposition of its rotation, Lthereby al- 35 lowing the diameter of the casing to be regu- .lated as desired and according to the size of.

Apipe after hav-ing been released therefrom,

' as described, 'I provide either end thereof arms E26 havopenings through which are received the .draw band27having a suitable draw -hold 28, by which said mold section may. be '55. grasped inorder to movethe saine longitudinally of Y theaifiolded section ofthe pipe, and as shown in the drawings, I' have p rovided the arms 26, so that 'when the casing is formed with bell or the like 14, and

said armsare 'secured to the inner wall of l Athebo'dy of the casing from which the bells areextended, itof course being understoodthat -Iiimay'omt the bells and secure the drir'i'swhere the casing would be substituted niediu'ni of set screws 25, which ass .through- Y 35, which are secured lmolding casing'l provide a shell 29, which has s ecured upon its outer surface, and :idjalcent its meeting edges, a 'similar.arrangement of levers and the operating shaft as heretofore described, and by which the easing 10 is adjusted to diii'erentsizes, it of course being understood that the shell Q9 iii-ay be'posi-v tioiied over the casing 10 and the thickness of the pipe regulated by t-lie relative dialneters of the casing andthe shell.

In the-inolding of dil'erent sized pipe sections, at` which tiine the relative diameters of the shell'ZQgand the casing 10 inust be changed, it is necessary that the base portion 23 should be'correspondingly changed so that t-lie rib 24,'will bereceived be tween the sections and lin order to provide for suoli changeyl provide the base portion with a central bracket 30, which ispreferably constructed of angle iron and bentin 'rectangular shape, the sides of the bracket 30 having revolubly but longitudinally iniinovably received therein, the ends of suitable adjusting bolts 31, the opposite screw threaded ends 32 of which are received within the adjusting brackets 33, which arecorrespondingly screw threaded and are secured j t-o the under face of the base'portions, all of such parts being preferably fornied of nietal.' It will thus be Aseen that by rotating the adjusting members 31 the four sectionsof the base will be moved outwardly or inwardly; as' desired, so that the circumference of the rib '24 .can be adjusted to suit the size of the pipe section which it is desired to niold betweenthe casing and the shell.

lVhen it is desired to forni a pipe. section within a ditch Iprvide aseinicircular mold 34, which niay be placed 'within the ditch with its open faoe upward, after which the casing is placed thereinto and the material of .which the pipevis to be foi-ined passed therebetween while in a green state. In order .to support the casing upon this seinicircular mold section, I provide the diametrically opposite sides thereof with supporting arms at one end to the casing, the-oppositc'ends of which extend outwardly therefrom at approximately right angles and are adapted to rest upon the upper edges of the mold 34.' To'regulate the diameters of the easingand shell so that different size pipes inay be molded, .I pro- -vide the meeting edges Awith recesses 3G, disposed diainetrically 4opposite to the adj ust:

ing means heretofore described, one of saic sectidns being provided witl tongues 1,37 rigidly carried thereby, sait tongues projecting beyond the edge of tln coacting sections and being provided with z seriesfof'slotted openings 38, adapted to re eeive the staples 39 and when secured in thi:

meeting l position they are? held therein by means o pins 40- disposed transversely through thl staples, such pins abei'iig preferably of-wedg shape, .so :force the tongues in cont-act Wit the outer face of-thel overlapped'sections. l It will thus be V,seen that bv' provid- .'ing" these tongues and staplestrfe tongues 'may adjusted to difrreiit,l positions, thereby increasing or decreasing the circumferen'ce of the -casing or s ell, independent of the aforesaid mechanism. Itis also apparent that in forming chimneys the outer shell -siectioiis are may be, done away With, the casing simply beingplaced Within' the brick chimneyand the material molded therearound, the lbrick portion serving in lieu of the shell.I

nection with the main pipe section, in the or Y joints, or to extend such connections at an angle therefrom, the said '-terial I.molded .therearound In order to A' driven into4 thc ground hold these sections in place a pin 41 may be and in contact With thel bell ,end of the joint, so as to` rigidly hold the same in position until the molded material has fullyl set, at which time said pin may be removedv and another section of pipe molded orjoined to said branch pipe, asdesired.

' y' The material trom which the pipes' arel .molded may be any desired composition matter, in a green state, b ut from experience, inix cement, sand and crushed rock or gravel, lime and sand and sutiicient- Water to thoroughly Wet the same, so that ivhen'compressed it will thoroughly co-agulate to form a non-breakable material. j f

It will thus be seenthat I have provided a mold for pipe sections or the like, 4which will permitpipe y.to be molded in any desired length and Without joints, and which `will further do away with -theleakage at such joints, Aas isl the usual objection to this manner of joining pipe sections.

It Will alsoA be seen that I have provided a very simple construction Whichwill permit the pipe sections to be molded at a, very rapid rate and wherein the mold forming sectionsmay be easily regulated to dili'erent size pipes, and vfurther my construction pernits the movement of the mold free of the molded section, Without the necessity of the nconvenient operation of reaching into the portion ofthe Where it is desired to make con-` placed in position and the maf or cement-.and sand mentally, adjusting pipe as has been a--further objection to other devices of this character.

Furthermore, ,the device may be applied for use in molding vlsemicircular sections of pipe or culverts, tically extended pipeivh'ich require a base for supporting thesame `and it will also be seen that coni'iectionsmay be made with a molded section of pipe at any desired angle and ir-'i-iajnyrposition along its length.
